As your days, so shall your strength be. 

When they arrest you and deliver you up, do not worry beforehand, or premeditate what you will speak. But whatever is given you in that hour, speak that; for it is not you who speak, but the Holy Spirit. § Do not worry about tomorrow, for tomorrow will worry about its own things. Sufficient for the day is its own trouble.The God of Israel is He who gives strength and power to His people. Blessed be God! § He gives power to the weak, and to those who have no might He increases strength.“My grace is sufficient for you, for My strength is made perfect in weakness.” Therefore most gladly I will rather boast in my infirmities, that the power of Christ may rest upon me. Therefore I take pleasure in infirmities, in reproaches, in needs, in persecutions, in distresses, for Christ’s sake. For when I am weak, then I am strong. § I can do all things through Christ who strengthens me. § O my soul, march on in strength!
